Muriatic acid is chemically identical to hydrochloric acid. The two names are used interchangeably.


Do not use combustible materials, like saw dust, to absorb neutralized acids. Do not flush acids into sewer systems.

Muriatic acid is a strong acid that has many household uses, including swimming pool maintenance and toilet cleaning, as long as you have plastic pipes. It is commercially available in liquid form, and like all other liquids, muriatic acid spills easily. Because many homes have carpet in them, muriatic acid may spill on carpet. Due to its corrosive nature, you can't simply blot up muriatic acid with a towel. You must clean muriatic acid spills with caution.

Step 1

Open windows and doors in the room where the spill occurred. It is important to adequately ventilate the room before cleaning up the spill.

Step 2

Put on appropriate personal protective equipment including plastic goggles or a face shield, a rubber apron and rubber chemical gloves. Cover or otherwise contain unspilled muriatic acid to avoid creating multiple spill areas.

Step 3

Apply an alkaline material to the spill site to neutralize the acid. Possible alkaline materials that are effective include soda ash, lime, ammonia and baking soda.

Step 4

Apply an absorbing material to the spill site to absorb the neutralized muriatic acid. Possible absorbing materials that are effective include soil, vermiculite, perlite, dry sand and other commercially sold absorbing products. Clean the contaminated absorbing material up and place all of the chemical materials into a chemical waste container.

Step 5

Take the chemical waste container to a chemical waste dumping area where the contaminated materials can be disposed of safely.
